To ail wir/m, it 71mg/ concern: arranged alike in both the fixed and movable Be it known that I, FREDERICK C. FLaDD, supports and for like adjustment, and so that ofMiddletown, in the county ofMiddlesex and when the arm O is thrown downward the two State of Connecticut, have inventedanew Irnedges will come substantially together and 55 provement in Sprue-Cutters; and I do hereby make a cut similar to that produced by the declare the following, when taken in conneccold-chisel in the hand of the workman, and tion with the accompanying drawings and the which is the usual method of cutting ot'f the letters of reference marked thereon, to be a sprue. By this apparatus the sprue is cut full, clear, and exact description of the same, without the shock to the casting unavoidably 6o ie and which said drawings constitute part of produced by the cold-chisel and hammer, and this speeilication, and represent, inthe breakage incident upon such shock is Figure l, a perspective view of the sprueavoided; but not only is this loss in casting cutter as arranged upon the bench ready for prevented, but the cutting is greatly facilioperation, broken lines indicating` the cutter tated, and the same werkman will accomplish 65 I5 as clcsed; Fig. 2, avertical section through the a much greater amount ot' work than can be recess, showing a side view of the cutter and done with the chisel and hammer. ofthe set-screw. By making the cutters i'rom a plain bar of This invention relates to an apparatus for steel, and the machine being` constructed with cutting the sprue from small castings, the obseats therefor, the end ot the cutter only re- 7o 2o ject being to provide a cutter so arranged that quires to be ground to sharpen it, and as it is the workman may ho'ldthe casting in his hand, thus ground away the set-screws will force it present the sprue tothe cutters, and then with outward, so that the bar may be almost enhis foot bring the cutters together to cut off tirely consumed in the machine. the sprue, and in such an apparatus as more rlhe arrangement of cutters describedmthat 75 fully hereinafter described, and particularly is to say, a holder constructed with a recess recited in the claims, my invention consists. corresponding to the shape of the cutter-bar, The apparatus consists of a base, A, conand with an adjusting-screwin line therewith strueted for attachment to a bench, B, and a to bear against and adjust the cutter, with a lever hinged to the base, one arm, C, extendcap to secure said cutter in its place-may be Se 5o ing forward, the other arm, D, rearward, and employed where one ot' the cutters is made rewith which arm a foot-lever, E, is connected ciproeating, as in a guided slide, instead of ou by a link, F, so that the operator placing his an oscillating lever. I therefore do not wish foot upon the lever may give it a swinging to limit this part ot' my invention to thelevers. movement, as indicated in broken lines, Fig. I do not claim, broadly, the arrangement of S5 3 5 1, and thereby impartan oscillatorymovement a cutter in its holder having combined thereto the arm O. The base A carries one cutter, with an adjusting-screw, by which the cutter c. The arm C carries thcsecoiid or companion may be adjusted longitudinally, as such, I am cutter, b. In the outer end ot' both the arm aware, is not new. and the base a recess, d, is formed, to receive I claim- 9o 4o the cutter. The cutter is best made from a 1. In asprne-eutter, the combination ot' two straight bar of steel correspondingin shape to cutter-holders arranged, one stationary, the the recessin the cutter-holders. Through the other having a reciprocating movement imbottom of the recess a set-screw, c, is iutroparted to it toward and from the one, each of duced, parallel with the recess, and so as to said holders constructed withavertical recess, 95 abut against the inner end of the cutter, as the recess in the one being in line with the reseen in Fig. 2, and on the set-screw is a jamcess in Ithe other, and each recess correspondnut, F, by which, after the screw has been ading to the shape ot" the cutter-bar, a cutterjusted, it may be set. Upon the outside of bar arranged in each of said recesses, their the cutter-holders-that is, as a cover for the cutting ends toward each other, the set-'screw roo recess and cutter-a cap, G, is arranged and in each of said holders in line with the cuttersecured by screws, as shown. The cutters are bar, and so as to form an adjustable abutment for each of said cutter-bars, and a cap removably attached to said holders, and so as to close the openV side of said recesses and hold the cutter therein, yet leave them adjustable by their own set-screws, substantially as described.

The base A, having a vertical recess, d, in its forward end, the cutter c, arranged in said recess, a set-screw. e, through the bottom of -said recess, and so as to abut against the inner end of the cutter, the cap G, arranged to close the front of said recess and support the p cutter,the lever hung to said base, one arm,
